DroneDeploy, developer of enterprise-grade drone software, announced it had closed a $35 million Series D round led by Bessemer Venture Partners.  Bessemer partner David Cowan will also join the Board.  Tracy Young, Co-Founder and former CEO of PlanGrid, a mobile construction productivity software tool, also joins DroneDeploy’s Board of Directors.

Drones are gaining favor among field workers on survey job sites across industries in construction, agriculture, energy, and more, DroneDeploy noted.  Investors see drone solutions as a major opportunity in a $6 billion global market.

The funding comes on the heels of a period of rapid momentum for DroneDeploy.  The company recently announced entry into the drone inspections market at its annual conference in San Francisco.  It also announced new partnerships with Airbus and drone hardware maker Skydio.  This latest round brings DroneDeploy’s total funding to $90 million; additional participating investors in this round included Energize Ventures, AirTree, Emergence Capital, Scale Venture Partners, and Uncork Capital.

DroneDeploy will utilize the funding to expand internationally, move into new industries, and further build out its suite of offerings for customers.
